MultiBit Bitcoin wallet information file (.info)
.info file signature | application/octet-stream
MultiBit Bitcoin wallet information file (.info) is a metadata file format used by the MultiBit wallet software, developed and maintained by the MultiBit project for storing wallet-related information. It is used to record details such as wallet settings, account data, and synchronization information for opening and managing Bitcoin wallets in the application. MultiBit is now a legacy, discontinued wallet, but .info files are generally safe and contain non-executable data; users should still handle files from unknown sources cautiously.

Frequently Asked Questions
What is a .info file?
A .info file is a MultiBit Bitcoin wallet information file file.

It is used to record details such as wallet settings, account data, and synchronization information for opening and managing Bitcoin wallets in the application. MultiBit is now a legacy, discontinued wallet, but .info files are generally safe and contain non-executable data; users should still handle files from unknown sources cautiously.
What are the magic bytes for .info files?
The magic bytes for MultiBit Bitcoin wallet information file files are 54 68 69 73 20 69 73 20 at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.
How do I validate a .info file?
To validate a .info file, read the first bytes of the file and compare them against the known magic bytes (54 68 69 73 20 69 73 20) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.
What is the MIME type for .info files?
There is no officially registered MIME type for .info files. Systems typically use application/octet-stream as a generic fallback when handling this format.
Is it safe to open .info files?
